采用某洗煤厂的煤矸石和天然黏土石灰石作为主要原料,添加适量的氯化铝制备吸附剂对Cr~(6+)进行吸附,运用SEM技术对吸附剂进行了表征,研究了不同因素对Cr~(6+)去除率的影响,并探讨了吸附机理。
Adopting coal gangue and natural clay limestone from a coal washing plant as the main raw material, adding appropriate amount of aluminum chloride to prepare adsorbent to adsorb Cr 6+, SEM was used to characterize the adsorbent. The effect of different factors on Cr ~ (6 +) removal rate, and discussed the adsorption mechanism.
